CHAIR BEDS'IEAD Filed March 23, 1936 4 Sheets-Sheet 4 Inventor PatentedJune 20, 1939 UNITED STATES PATENT OFFICE Application March 23, 1936,Serial No. 70,451 In Poland March 26, 1935 1 Claim.

llhe invention relates to improvements in chair bedsteads and concernssuch a construction of these chair bedsteads in which the bed bottomconsists of three parts having an equal or a nearly equal length, amiddle part provided with a stationary base and two side parts to bepulled out laterally from the said base.

The main objects of the invention are, first, to obtain a chair bedsteadof the above mentioned kind having as chair a quite chairlike and afterbeing expanded a quite bedlike appearance, second, to obtain a chairbedstead occupying as chair the place of a normal chair of this kind andhaving after being expanded the surface of a normal bedstead, and third,to obtain the aforesaid results in a chair bedstead which requires onlya few simple manipulations for its transformation into a bedstead orvice versa.

The invention is shown by way of example only in the accompanyingdrawings in which:

Fig. 1 is a front perspective view of the device in position to be usedas a chair.

Fig. 2 is a side view of the chair bedstead,

Fig. 3 is a front perspective view of the chair transformed into abedstead,

Fig. 4 is a front perspective view of the chair during thetransformation, 1. e. of a chair only partly transformed into abedstead,

Fig. 5 is a side view partly in section of the middle part of theupholstered chair without the lateral arm portions,

Fig. 6 is a vertical section corresponding to Fig. 4,

Figs. 7 and 8 are a side view and a fragmentary side view of the chairbedstead showing the details of the mechanism without the lateral armportions.

Figs. 9 and 10 are perspective views showing 40 the use of stopslimiting the pulling out of the side parts of the bed bottom from itsmiddle part,

Fig. 11 is a front view of the stop corresponding to Figs. 9 and 10,

Fig. 12 is a side view of a roll for the cable and of its support,

Fig. 13 is a front view corresponding to Fig. 12, partly in section,

Fig. 14 is an eye-bolt for the cable.

The upholstered chair according to this invention comprises a rigidlower part or stationary base a (Figs. 1, 2), a superposed upholsteredframe b upon which a cushion d is placed, an upholstered back frame orlean support a with 55 a back-cushion f, two lateral upholstered orrigid arm portions b and c, and a not upholstered frame or plate 0. Asshown in Fig. 5, the front and the back side of the base a are alongtheir upper edges provided with T-shaped guide rails t. The said frame bslides above and outwardly of these rails it, while the frame 0 slidesbetween the said rails t and below the said frame b. The said frame 0 isrigidly connected to the lateral portion 0' (Figs. 4, 6, 7), and theupholstered frame b is rigidly secured to the lateral portion 1). To theupholstered frame b two cables h (the one near the front, the other nearthe back side of the chair bedstead) are secured. These cables 71.extend over rolls I and through the eye-bolts 2, both rolls andeye-bolts placed on the base a, to the lateral portion 0'; two cables hare secured in a similar manner to the not upholstered frame 0 andextend over the rolls 3 and the eye-bolts 4 to the lateral portion b ofthe chair. One cable It and one cable h are shown in Fig. 6, but twocables h and two cables h are shown in Figs. 7 and 8. The arrangement ofcables h and h with their rolls and eye-bolts causes every movement ofone lateral portion to be followed by a corresponding movement in theopposite direction of the other lateral portion.

Forthe transformation of the chair according to the invention into abedstead only the following three manipulations are necessary. First,the pulling out of one of the lateral portions b or c, is followedautomatically by the simultaneous pulling out of the other lateralportion and of both frames b and 0, second, the folding down of the backframe or lean support e which is pivoted on four hinges g placed two andtwo on twoopposite sides of the stationary base a, across the said base,third, the placing of the cushion d on the frame 0. The upholsteredframe b, the folded down back frame e and the not upholstered frame 0,the latter covered by the cushion d, form then the upper surface of thebed bottom.

In case of chair bedsteads not provided with cables an additionalmanipulation for the pulling out of the second lateral portion isnecessary.

The transformation of a bedstead accordingto the invention into a chairdemands as a contrary process always the same number of manipulations.

The small plates or stops 2' are arranged to limit the pulling out ofthe side parts.

The open chest min the stationary base a may serve as bedding container.

I claim:

A chair-bed comprising a stationary base, a

said base and a pair of cable systems, each of the cable systems beingconnected to one of said side frames and trained over the pulley meanson the corresponding side of said base and connected directly to theopposite side frame.
